TRANsoM AnJUsTER.

Application led April 1, 1925. Serial No. 19,984.`

uniform manner so as to avoid any chance' of slamming it closed or pulling it Wide open suddenly; also to provide this means in a simple and inexpensive iforin and provide a number of minor improvements.

Reference is to be had to the accompanying drawings, in which Fig. 1 is an elevation of the door casing and transom with a preferred embodiment of this invention applied thereto;

Fig. 2 is a side view ot the same partly in section;

Fig. 3 is a plan onv enlarged scale of apart of the operating device;

Fig. 4 is a bottom plan of the oint for the links; and

Fig. 5 is a side View thereof. Transom litters now on the market usually involve a sliding motion and as constructed theyoften stick so that in closing a transom it is hard to start the device and When it is started the transom is likely to close suddenly With a bang. This sometimes breaks the glass and at any rate the operation is disagreeable.

For the purpose of avoiding these diiiculties and providing Ya smooth working device I locate the rotaiyoperating handle or crank 1() at a convenient point on the casing on a horizontal shait 11 which by gears 12 drives a vertical shaft 13 having a Worm 14 at the top. This worm .operates a gear or Vsegment 15 fixed on a shaft 16. On lthis shaft is positively fixed an arm. 17 to swing With it. This arm is connected by a rpivot pin 18 with a link 19 which is pivoted to a. bracket 20 on the rear of a vertical tranom sash 21 Which is hinged at 22. TheV line of hinge pivots 22 on Which the sash turns is located below the shaft 16 but parallel therewith. It is also located beloWthe pivot pin Y 18 and Ais arranged usually to be substantially underneath it When the' transom is Wide open. s

The arm 17 and link 19 Where they meet are provided With stops 23 and 24. These consist merely in bending the ends of the arm and link respectively over toward each other so that they meet on one side of the' pivot 18to limit the motion of the shaft 16 to the position shown in Fig. 2. 1n other Words, when the transom is opened as rfar as it can be by thestraightening out ot these links, the crank 10 cannot be .turned any further in4 that direction. This is desirable e0 f because if it were' not for it thek operator.. v-

mi ht Oo on tui-nin inthe same directionV b and close the transom again or at least turn it back. l ,Y

X/Vith this construction the operat-ion of the crank 10, starting from the position Although I have illustrated and described only a single form of the invention I am aware of the fact that modificationscan be made therein by any person skilled in the art Without departing from the scope of the invention as expressed in the claim. Therefore I do not Wish to beY limited to allthe details of construction herein shown but WhatT do claim is 'y i In a device for operating a vertical transom pivoted on a horizontal axis at its lower edge, the combination of a horizontal Shaft above said axis and at one side thereof, means for rotating said shaft, anarm fixedy to the shaft, and a link pivoted to the free end of the arm and to the sash of the transom at a point above the shaft, whereby when the shaft is turned in one direction and the arm turns with it, the sash will swing` f open on its pivot, t-he link and arm being arso as to exert al powerful leverage to close the sash and hold it closed when the link and arm are moved inwardly into horizontal position.

In testimony whereof I have hereunto affixed my signature.
